My friend told me when she was delivering her son she went into cardiac arrest and was hovering over her body and saw her grandmom and was told to go back, cause it was not her time yet. While she was hovering over her body she saw the medical staff doing cpr and one of the med students was so upset he threw up on the floor. After she was back in her body she asked the student how he felt, and everyone was freaked out that she knew he got sick since she was in cardiac arrest when it happen.

There's a possibility all of these stories are the result of drugs, mental illness, physical illness, stress, sleep paralysis, dreams, or natural phenomena misidentified. That all of these stories are the result of the story teller lying or exaggerating.
But out of all the hundreds of stories here there is also the very real possibility that perhaps one is the absolute truth, that one has no other possible explanation other than the supernatural.
The question is, which story is it and what would that suggest about the universe.
